EV9 not archiving smime messages

After upgrading from 8.0.2 (with the smime hotfix 338323) to 9.0.0 digitally signed emails no longer archive. This is the same problem I had before applying the hotfix to 8.0.2. Is there a separate hotfix for 9.0.0? Can I run the same hotfix on 9.0.0 that I ran on 8.0.2 to fix this?

Tony is right, unfortunately a regression was introduced in EV 8, after the hotfix was produced, which meant that some versions of EV 8, and EV 9 had the issue "reintroduced". As Tony says, that's the hotfix for it.. it was released on or about the day that EV 9 was released, I think.
